The LED display screen can only display text content from the previous two primary colors of red and green. After the maturity of blue LED technology, three primary color LED display screens have been born, so that the display content can be displayed with pictures and texts and play dynamic videos. LED large screens are widely used in various occasions such as indoor and outdoor large-scale advertisement broadcasting, stage performances, exhibitions, sports events, hotel lobbies and so on. LED display has the advantages of large display area, flexible size and specification, high brightness, bright color, easy assembly, high utilization of building space and low maintenance cost. The models of indoor LED electronic screens are: P1.6, P1.9, P2, P2.5, P3, P4, P5, etc. The numbers represent the distance between the light-emitting points (lights) on the display, in units of All are mm. For example, P3 indicates that the distance between the adjacent two groups of lamps is 3mm; P4 indicates that the distance between the two groups of lamps is 4mm. As can be seen from the above models, the smaller the number, the smaller the distance between the lights on the display. For example, everyone will understand. The same one-square-meter display has 62,500 points on the P4 display, 111,111 points on the P3, and 160,000 points on the P2.5. The smaller the number, the higher the density of the lamp, and the higher the resolution of the display screen. Of course, the production cost will be higher.
Tips before purchasing high-definition LED display:
Since the transaction amount of LED full-color display is generally high, ranging from tens of thousands to hundreds of thousands or even millions, customers need to be particularly cautious when choosing LED large-screen suppliers. Must not be completely price-centric, without excellent quality as the benchmark, no matter how cheap the price is meaningless.
- Comparing the price under the same quality of the display screen, paying attention to the quality will pay a price, and ignoring the quality will cost more
- Verify the scale, output value, and after-sales service capabilities of suppliers.
- Confirm that the technical parameters/configuration list of the LED display is true and effective.
- Confirm whether the contract price of the large screen is complete, and avoid other fees raised by the supplier after signing the agreement.
- If conditions permit, the manufacturer should be invited to the installation site to check or take pictures to confirm whether the site meets the installation conditions. If not, a detailed solution should be proposed.
- If conditions permit, you should go to the manufacturer’s factory for physical inspection, watch the actual effect of the LED display product on the spot, and choose the most suitable LED display product for you.
